Some problems that are damaging Earth
Earth is the planet that we live on, therefore, it is important to look at the problems that it is facing and try to solve them. These problems also affect us negatively. Some of these problems are:
Waste disposal and management
Climate change is when the average long-term weather patterns of a region are altered for an extended period of time, typically decades or longer. Examples include shifts in wind patterns, the average temperature or the amount of precipitation. These changes can affect one region, many regions or the whole planet.
Climate changes are caused by changes in the total amount of energy that is kept within the Earth's atmosphere. This change in energy is then spread out around the globe mainly by ocean currents as well as wind and weather patterns to affect the climates of different regions.
Global warming and the climate changes seen today are being caused by the increase of carbon dioxide (CO2) and other greenhouse gas emissions by humans.
Human activities like the burning of fossil fuels, industrial production, etc. increase greenhouse gas levels. This traps more heat in our atmosphere, which drives global warming and climate change.
CO2 concentrations in the Earth's atmosphere has increased significantly since the beginning of the Industrial Revolution, and most especially in the past 50 years.
The impact of these shifts have an impact on all life-forms on our planet including their sources of food and water. Current impacts that are already being observed are desertification, rising sea-levels as well as stronger extreme weather events like hurricanes and cyclones.
Simple ways in which we can reduce climate change
Reducing, reusing, and recycling in your home helps conserve energy and reduces pollution and greenhouse gas emissions from resource extraction, manufacturing, and disposal. If there is a recycling program in your community, recycle your newspapers, beverage containers, paper, and other goods. Also, composting your food and yard waste reduces the amount of garbage that you send to landfills and reduces greenhouse gas emissions.
To improve your fuel economy and reduce greenhouse gas emissions, go easy on the brakes and gas pedal, and avoid hard accelerations.
Renewable fuels (made from renewable sources such as corn) that can reduce greenhouse gas emissions from your vehicle. E85 is a fuel blend containing 85% ethanol and 15% gasoline that can be used in certain vehicles called Flex Fuel Vehicles (FFVs). FFVs are designed to be fueled with either E85 or traditional gasoline. There are millions of FFVs on the road today—to find out if you own one, check the inside of your car's fuel door for an identification sticker, or consult your owner’s manual.
Why is conserving water important?
Fresh, clean water is a limited resource. While most of the planet is covered in water, it is salt water that can only be consumed by humans and other species after undergoing desalination, which is an expensive process. Occurrences such as droughts further limit access to clean and fresh water, meaning people need to take steps to reduce water use and save as much water as possible. In some areas of the world, access to water is limited due to contamination. People who have access to fresh water can take steps to limit their use of water to avoid waste.
People should do their best to conserve water for three reasons. The less water used or wasted by people, the less clean water will become contaminated. In some cases, using excess amounts of water puts strain on septic and sewage systems, leading to contamination of groundwater, as untreated, dirty water seeps from the sewage system into the ground.
Water conservation reduces energy use and can even save households money. Most families pay to use water in their cities or regions. The less water a household uses, the less they have to pay each period. Appliances that use water, such as washing machines and dishwashers, also use a considerable amount of energy.
Conserving water now allows cities and regions to plan for more efficient use of the water resources in the future. If most of an area's clean water is wasted, there will not be water for future generations to use, meaning the city will need to come up with new ways to produce clean, fresh water, which will ultimately be at the taxpayers' expense.
Simple ways in which we can conserve water
People can save water by making smart choices at home. They should only use appliances that rely on water when those appliances are full. For example, a family should wait to use the dishwasher until it is completely loaded with dishes. Surprisingly, using the dishwasher uses less water than washing by hand. Other ways to conserve water include taking shorter showers and only watering gardens and lawns when necessary.
Read the house water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, there is a leak.
Clean the car using a pail of soapy water. Use the hose only for rinsing - this simple practice can save as much as 150 gallons when washing a car. Use a spray nozzle when rinsing for more efficient use of water.
Why is conserving energy important?
Energy Conservation is unquestionably of great importance to all of us, since we rely on energy for everything we do every single day. Energy supplies are limited and, to maintain a good quality of life, we must find ways to use energy wisely.
Reducing the amount of energy that we use is a good way to save money, and there are also other benefits to decreasing energy consumption. For example, a large portion of the energy we use is derived from oil. Some experts claim that we will run out of oil in just a few decades. As natural resources used to produce energy become scarce, the cost of energy will most likely increase. Also, toxins and pollution are released into the atmosphere during the production and consumption of energy. Not only we are running out of some valuable natural resources, but we are also destroying the environment in the process of using them!
Embrace energy conservation by making small changes that will lead to a significant difference in our overall energy consumption. Your efforts, combined with those of others who have chosen to make a few small changes too, will benefit your life and the lives of future generations, as well as our environment.
Useful tips for conserving energy
Unplug! Up to 75% of the electricity used to power home electronics is consumed while the products are turned off. Appliances like computers, tv’s, cable boxes, cell phone chargers, coffee makers, etc. all continue to consume energy just by being plugged in into an outlet.
Set your thermostat at 78 degrees or higher in the summer. Use fans whenever possible instead of AC, and ventilate at night this way when practical. Using fans to supplement AC allows you to raise the thermostat temperature, using less energy. Fans cost less to use than AC.
Keep the thermostat at 70 degrees or lower in the colder months. Turn down the thermostat at night to 65 degrees, lower when you go to bed or leave your house for more than four hours.
Clean the lint filter in your dryer after every load to improve air circulation, and periodically check the dryer vent to ensure it is not blocked.
Turn lights off in unoccupied areas, including porch lights when you go to bed.
Buy light bulbs that are 60 watts or less. Even better, get energy-saving compact fluorescent lights. They last much longer and you won’t have to change them as often.
Make sure the dish-washer and clothes-washer have full loads before running them. Use the “air dry” setting on the dishwasher. Wash clothes in cold water when possible and rinse them in cold water.
Set your refrigerator temperature at 37 to 40 degrees and your freezer at 0-5 degrees. Close the door quickly after you select an item.

Check air conditioner filters each month. Dirty filters block air flow, increasing your energy bill.
Why is proper waste disposal and management important?
Proper waste disposal is critical due to the fact that certain types of wastes can be hazardous and can contaminate the environment if not handled properly. These types of waste also have the potential to cause disease or get into water supplies. There are rules and regulations in place for how specific types of waste should be disposed of. Following them allows for toxic waste to be safely discarded without the risk of environmental contamination.
Hazardous wastes that are not properly disposed of can leak and contaminate soil and water, which can lead to issues with both the environment and human health. Burning the wrong types of waste can release gases into the atmosphere. When waste is properly discarded, special liners are used to prevent toxic chemicals from leaking out and precautions are taken so that any methane related to burning trash is safely contained.
When waste is disposed of properly, it helps to prevent additional pollution which can improve public health. Polluted air increases the risk of respiratory illness. Waste that is properly disposed of has a lesser chance of getting into the water supply and causing illness. In the 1980s, there was an incident in New Jersey in which unregulated dumping led to a chromium poisoning epidemic in a local school.
