It is very important to protect the environment and prevent it from being damaged.If we continue cutting down forests,polluting water sources and releasing toxic chemicals into the air then the after effects can be disastrous.Destroying forests cause millions of animals to lose their homes and lost of plants that are vital to people since they take in carbon dioxide in exchange for oxygen.Polluting water sources with trash kills many aquatic animals and can greatly affect the food chain.The release of toxic chemicals into the air from factories and gaseous emissions also affect our health negatively.Global warming has appeared because of this and is causing ice from polar regions to melt,resulting to sharp rises in water levels.These things may not affect us now,but it will affect future generations so we must prevent any further damage to the earth by taking action immediately.
