THOUGH scientists warn that global warming will likely continue for centuries because of the long natural processes involved, there are a few things teachers can do to decrease the effects. Basically, they all boil down to this: don’t use as much of the stuff that creates greenhouse gases. On a local level, you can help by using less energy.
The electricity that operates many of the devices in our homes comes from a power plant and most power plants burn fossil fuels to generate that power. Take shorter whowers to use less hot water. Use a fan instead of an air conditioner on a warm day.
Here are some other specific ways teachers can help decrease greenhouse gas emissions:
1) Make sure teacher’s car is properly tuned up. This allows it to run more efficiently and generate fewer harmful gases.
2) Teachers can walk or ride bike to school if possible, or carpool on your way to school. Cars burn fossil fuel so smaller, more fuel efficient cars emit less CO2, particularly hybrid cars.
3) When teachers are not at home, please turn lights and other appliances off. If can, teachers may switch from incandescent light bulbs to fluorescent bulbs, which use less energy and last longer.
4) Recycle. Garbage that doesn’t get recycled ends up in a landfill, generating methane. Recycled goods also require less energy to produce than products made from scratch.
5) Teachers can plant some trees and other plants in the school compound or in their house garden. Plants take carbon dioxide out of the air and release oxygen.
6) Don’t burn garbage. This releases carbon dioxide and hydrocarbons into the atmosphere.
To really stem the emission of greenhouse gases, we need to develop non-fossil fuel energy sources. Hydro-electric power, solar power, hydrogen engines and fuel cells could all create big cuts in greenhouse gases if they were to become more common.
