Introduction Over-fishing, over-grazing and over-harvesting are the top disasters that are now on earth. Over-grazing means that too many animals are placed to graze in one small area. Overfishing means that people are catching too many fish, then the fish cannot reproduce fast enough to keep their population. Over harvesting means taking more from the soil and water than it can ever replace.
Over-Fished- People use newer technologies to catch even more fish.
Over-Grazed- This is a picture that the land is over-grazed
Over-Grazing Overgrazing is bad because animals are eating too much then the plant population decreases. The plants and grass do not get the chance to grow back. Instead they die out. This is caused by farmers or people that put too many animals in a small area to eat.
An area that is over-grazed with many animals eating plants and grass
Over-Fishing Overfishing is causing fish to become extinct. People are catching more fish than can be replaced. One of the countries that catches the most fish is Japan. People in Japan and other countries are causing fish to become extinct by catching fish faster than the fish can breed. Scientist say that if people continue to catch more fish than they are supposed to, then in the future we will have no fish. Some even say that fish at this time are becoming extinct, like the Blue fin tuna fish and sharks. People say that in the year 2048 they will become extinct completely.
This is a graph that shows the fishing over time.
Over-Harvesting Over-harvesting is taking more from the land and sea then it can replace, like extreme farming and watering. If people keep on doing this then our land and animals habitats can be ruined. There can be a big impact to our land and sea if people keep on Over-exploitation.
The disaster for over-harvesting is destroying habitats..
Does It Really Affect The Environment?
Over-fishing, over-grazing and over-harvesting is effecting the ecosystems. these problems are still happening now and these problems can change our lives. They are effecting the environment because they are causing animals to die and habitats destroyed. The number of fish we catch is increasing because they are catching more then before and about every year they increase.
Conclusion If people keep on making these problems then animals can die out completely. Now some people are helping the disasters that humans are making and these mistakes should stop I think that governments and presidents should make this a law not to over fish, graze and harvest.
Glossary Extinct- Means that a whole species of a animals is dead.
