Envronmental engineering is the combination of science and engineering to improve the condition of the environment. It is used to remove pollution to make the Earth a safer place for animals and humans. One of the ways environmental engineering is used is by recycling. Engineers study ways to stop air pollution such as car exhaust and industrial air pollution.

Chemistry and chemical engineering is used in aiding the oil clean-up because various chemicals can be added to the water to possibly make the oil easier to clean-up, but the chemicals that have already been added to the water are now harming the marine life and engineers need to find a way to get those chemicals out of the water possibly through other chemicals. Chemistry is very important in the efforts to clean-up the oil, but the engineers need to be very careful with the Chemicals they put into the water because the could be more harmful then the oil which has already happened and once a chemical is in the water, there is no way of reversing the situation. They also need to make decisions very fast which puts pressure on them to fix the problem of the oil spill that may lead to mistakes that don't end up solving anything. Chemicals can be very dangerous and Chemical engineering is a dangerous job because the engineers handle chemicals that are hazardous to them and to the animals they are attempting to save.

Environmental engineers can be chemical engineers or they can specialize in another field, but they are all very Imporant to the well being of the human race and the animal kingdom. They fix the mistakes humans and companies make. Without them, there would be no hope for a clean, pollution free future. Even with them, there is no chance that they can reverse what has been done to the Earth, but air and land pollution
