Answer:
The topic we were given is to explain how changes in Earth’s systems affect the growth of life on Earth. We will talk about three main things that are a part of this statement which will be; how life affects the climate system, how species can survive, and how do we know about this.
In our introduction we talked about how life affects the climate system. In very short terms, we can conclude that life affects the composition of the atmosphere. We can also conclude that it affects the climate as well because if we apply what we learned in the labs about how different materials absorb heat at different rates then we will see that when you have different life forms that are taking in and releasing gases such as carbon dioxide, methane and oxygen, that they too even have different rates at which they do it. Which backs up the point that it changes the composition of things. So when we have climate changes, not only are the species, but also our ecosystems are. They respond to these scenarios by adapting, migrating or even reducing their own population. Some examples in our own lives would be droughts, heat increasing, and even insect outbreaks. Which all link to climate changes, and even wildfires that occur. Some concerns are that we could have declining water supplies, health impacts in cities due to heat, reduced agricultural yields, and finally erosion and flooding in coastal areas are also very big concerns for us.
How can our species even survive? You may ask,well I will tell you how. Three simple things: move, die, adapt. It's sad to think of what we could be doing to our own ecosystems and animals. The thing is that as time goes on and the more climate changes there may not even be much left. Most animals will either adapt to the climate or move higher trying to escape the hotter weather. Scientists have been making assumptions that maybe it's changing too fast for them to do anything. Because the truth is that why would you want to die voluntarily. I can see why with older animals, but why with younger ones? They could want to run, but the thing is that they don't have a choice. Extinction of living things is one common fear. One day we could all go poof with any word being said, and that should be frightening to people. Adaptation could be the only way we brave through it.
The other part of this is how do we even know about climate change exactly? Over the years we have had many physical and biological changes that are confirming our theory about climate change. The retreat of glaciers, the melting of them and the ice is one big give away as well. Also the intensification of rainfall events, changing in the timing of the plants that are leafing out, range of some species that are shifting, and finally the arrival of migrant birds in springs. We also can see that human activity is also a reason for it changing as well as other things. There is evidence that we can not deny or ignore.
In conclusion, how life affects the climate system, how species can survive, and how we know about this, all play apart in the big story called climate change. It bears the truth that one day will not be pretty or just a concept, it will be utter reality. Until then there is another tomorrow, another week, another month and another year. See you on the flip side of things! Pure truth will one day be exposed, so will the mind of people and things.

I gathered facts from well known articles! Its a short writing as well i hope.
