Humans have an impact on ecosystems because they change the land to their benefit by not caring about the other life around them. For example, the humans channelized the streams so they could grow sugar cane to sell. Sadly, they did not think of returning the water to the streams so they dried out and all the plants and animals perished. (How do you protect yourself in a flat bare stream?)

I can preserve the stream and other ecosystems by picking up ôpala or making signs so other people can pick it up too. Together, we can help preserve our ecosystem, one ôpala at a time.

Humans have the most impact on the stability and diversity of ecosystems. I feel this way because if humans wanted a change in the direction of the streams they could easily divert it. But there’s a problem with the way we divert streams now. That problem is we don’t return the water. That’s the difference between the way our ancestors made took care of them and the way we treat streams today.

Some ways we can help Hawaiian stream life is to start protests based on not making channelized streams and returning more water to its original place.

I think humans have a big part on the ecosystems because they can introduce plant and animals, but sometimes that’s bad because if you think about it and you put a carnivorous fish in a fish pond, he will eat the other fish.

We the humans have the power of diversity and stability over the stream life. We have a choice of throwing the rubbish on the ground or where it is supposed to go. But where does a lot of it go…on the ground. The trash will find a way to go to the the ocean and maybe it could hurt an animal. And that could upset the balance between the ocean and the humans.

I think I can throw my rubbish away where it is supposed to be thrown and if I had a chance to pick up some of the rubbish on the beach so an animal wouldn’t get hurt or even die, I will do it.

People have a humongous impact on ecosystems because they have the power to do a lot of things to ecosystems. For example, we have the power to divert water to places and that will totally impact stream life by diverting the water.

Humans have an impact on the diversity and stability of stream life throwing their rubbish away. If some person doesn’t care about animals, then they might throw their plastic bag down a storm drain. It might get eaten by a animal and that will mess up a lot of things.

I can personally help stream life by making sure I use green (environmentally friendly) products. I also will not litter and let it go down storm drains. I also can ask my dad not to use fertilizer so when it rains, it doesn’t wash all the poison down the drain.

Humans have a huge impact on the ecosystem because if we litter it can trigger so many things. For example, if I drop a candy wrapper on the ground and it goes into a storm drain, it goes out to streams. Fish might think it’s food and eat it. They can choke and predators who eat those fish might die because they don’t have any food.

Humans have an impact on the diversity and stability of the streams because one little thing like dropping trash on the ground upsets the balance of nature.

I can pick trash that has fallen out of trash cans and put it back in, and make sure that it can’t fall back out. I can also try not to use as much soap to wash my parent’s cars.

One example is that if part of the stream is channelized, all of the dirt from the top comes rushing down the rest of the stream murking up the rest of the stream. Also, another way it could mess up the stream is if the water in the channelized part of the stream doesn’t get water, the bottom part of the stream won’t have water

An impact that the humans have on the ecosystem is that we channelize the streams. We also take the water off of the streams too. We humans have an impact on the diversity because we use too much water and take it out of the streams. Streams are a part of the ecosystem.

I can help to preserve Hawaiian stream life by stop polluting the streams.

Humans have control over the ecosystem that is stream life. Humans have a huge impact on stream stability because of the fact that people along with the animals need water to live ,and without it then everything will die.

I can pick up anything that doesn’t belong in the streams and the sea. I can save the water that my house uses by turning off the faucets while brushing my teeth and washing the dishes.

Humans can impact an ecosystem by polluting it, therefore, destroying it; or cleaning it, therefore, helping it live and maybe even making it better.

You can personally help preserve a stream by cleaning it up after a big storm when trees and branches fall into it, and on a regular basis, clean the invasive species out of it.

We humans have an huge impact on the stream’s ecosystems because if we do pollute the streams, we won’t have any more fresh, clean, pure water to drink and our population would die off. Also if we dumped all our aquarium fish into the streams, then we might not have all the good fresh water food to eat.

I can help and do my part by telling my family members to not let all their garbage go down into the sewer drain, then their friends might tell others. Also I will tell my family members to not dump their aquarium fish into streams and their friends might do the same thing.
