tudents learn about three examples of human impacts on marine life: migration patterns and shipping, algal blooms and water chemistry, and marine debris. Some of these impacts are due to human activity in the ocean, and some impacts on the ocean are due to human activity on land.

Humans are now responsible for causing changes in the environment that hurt animals and plant species. We take up more space on Earth for our homes and cities. We pollute habitats. We illegally hunt and kill animals. We bring exotic species into habitats. All of these activities take resources and habitats away from plants

we are not good because we litter,throw are trash on the ground ,don't clean up after are self

We are not good to our habitat because we have littered,wasted food,wasted paper,wasted water,wasted electricity,having toxic chemicals,improper disposal,car travel,air travel,ignorance the reason ignorance is hurting our environment is because if we want to make better changes and no one listens nothing with happen to make the earth.The reason air travel is bad because it makes so much co2 that it is harming so many humans and when the plane take off there is so much smoke that it's enough  to kill a person.The reason car travel is so bad is that because there is so much smoke that it is bad for the air.The reason improper disposal is bad because people put things like water bottles in the garbage and not recycling so they can't reuse it.Toxic chemicals are bad because if you leave them somewhere they can get knocked over and spill into a river lake or ocean.Wasting electricity is bad because if you leave a light on it will use more energy and one its bad for the environment two we just made are parents electricity bill more expensive.

When humans destroy wild land to build homes, factories, shopping malls, amusement parks, garbage dumps, even to build a visitor center, store and restaurant in a park, the land is changed. The animals that once lived there, from the bugs that lived in the ground to the birds that ate them, all may disappear. Some can move to new home areas, but there are already other animals living there. There is not enough food, water or shelter for all of them. Many of the animals will die.

I Think we affect the habitats of the living animals. wen we trample on then it hurts the animals cause they dont knowe where to live. so we should stop breaking them. or they might break ours.

The Human Touch
Humans are now responsible for causing changes in the environment that hurt animals and plant species. We take up more space on Earth for our homes and cities. We pollute habitats. We illegally hunt and kill animals. We bring exotic species into habitats. All of these activities take resources and habitats away from plants and animals.

Human activity often changes or destroys the habitats that plants and animals need to survive. Because human populations are growing so fast animals and plants are disappearing 1000 times faster than they have in the past 65 million years. Scientists estimate that in the 21st century 100 species will become extinct every day.

Natural Extinction

Animals and plants have always had a hard time surviving. Scientists estimate that over two thirds of the animals and plants that once lived on Earth are now extinct.

Animals became extinct in the past for a wide variety of reasons. In some cases competition for resources among animals led to extinction in other cases environmental changes caused extinction.

Scientists think dinosaurs became extinct because a meteorite struck the Earth and caused changes in the environment that the dinosaurs and other animals and plants couldn't adapt to.

Multiple Factors

Some animals are endangered because of a combination of natural and man-made causes.

The West Indian manatee is an endangered aquatic mammal that lives in rivers, estuaries, canals and saltwater bays.

Manatees need warm water to survive. In the winter they live in southern Florida and parts of Georgia. In the summer they can migrate as far north as Virginia and west to Louisiana. Sometimes manatees die because they don't migrate back to warm water soon enough.

There are currently a little under 2,000 manatees in Florida. Every year about 150 die. Manatees are often killed when they are hit by boats. Manatees can also die when they get caught in fishing nets. Manatees only give birth every two to five years and they only have one calf at a time. Because their reproduction rate is so low and mortality rates are high, manatee populations are endangered.

Longing for Lupine

Some animals, like the Karner Blue butterfly, are endangered because they need very special environments to survive.

The Karner Blue is dependent on the wild lupine. The wild lupine is a plant that grows in pine and oak barrens in the Northeast and Midwest. It is the only known food source of the larvae of the Karner blue. Without this plant the butterfly can't survive.

Wild lupine grows best in sandy soils where forest fires occasionally clear out old vegetation. Fire helps keep shrubs low and clears the areas of plants like aspen and maple that can take over the area and create too much shade for lupine to grow.

Karner blues rely on lupine for their whole life cycle. They attach their eggs to the stems of the plants and newly hatched caterpillars eat the leaves of the plant. If wild lupine doesn't grow, the Karner blue doesn't survive. Because humans control wildfires, lupine isn't as abundant as it used to be. Lupine is also killed by pesticides. Because lupine is harder to find, the population of Karner blues has drooped by 99 percent in the last two decades.

Unfair Competition

Some animals are endangered because exotic or non-native species were introduced to their habitats. In Hawaii, the state bird, the Nene Goose, is in danger, in part, because of the mongoose. The mongoose was brought into Hawaii by planters to help control rats in sugar cane fields. The planters didn't realize that rats are nocturnal and the mongoose hunts in the day. The mongoose found other sources of food like eggs from nesting birds, including the Nene goose. The Nene goose used to be found all over Hawaii. There are now less than 800 left in the state.

50 out of 50 because for the yes part people somtimes help nature because people somtimes pick up garbage and rake leaves just in case there is somthing under the leaves that could hurt the animals and no beacuse people drive cars and pulute the air and some people dont care and they just drop garbage on the ground and leave it there for example someonesn drinking a pop and there done and they just look around for a minute and then plop its on the ground and animals need there homes and once i saw someone find a snake hole and they were filling it with dirt so that the snke couldent get in or out. madelynn

building a house will hurt the world its like taking a peace of the world but if u use a cave its not hurting the world whats bad about it is ur food will get rotten if not in somthing.if u want to build a city its not only hurting the world but its stealing animals homes so they have to live in another place.your also stealing there food because they cant carry all there food and if u upgrade ur town it will take more space for less animals and they will die
