My wonder question is how long will life on earth last for? Is there a way to prolong existence? So, I am talking about how to stop extinction. Extinction is the death of all of the individuals in a species. This means the species cannot produce enough offspring to replace the deaths of members of the species. Environmental changes are the most common causes of extinction. Humans are often the cause of environmental changes leading to the extinction of animals. Fun fact, most of the plant and animal species that have lived on earth are now extinct. The most well-known mass extinction occurred at the end of the Cretaceous period, about 66 million years ago. Almost half of all known species disappeared.
Life on earth will be wiped out eventually. But how long do we have? The fossil records have told us that life on earth has lasted around 3.5 billion years. In that time earth has survived being frozen, taking a beating by rocks from space, mass poisoning and lethal radiation. So, its hard to completely sterilise the earth.
Some ways to stop extinction are to stop burning fossil fuels. Burning fossil fuels and cutting down rainforests is heating up the atmosphere. This is creating trouble all over the world, especially for coral reefs which are being destroyed as the oceans are becoming more acidic. The world needs to be off fossil fuels this century if we want to limit warming to at the most 2 degrees Celsius. Researchers have shown we can do it with existing technology like wind, solar and nuclear.
Another thing we can do to prevent extinction, is to fight illegal wildlife trafficking. Some of the worlds most classic species like the elephant and the rhino are threatened with extinction because people are killing these amazing creatures for their body parts. People sell elephant ivory that are carved into trinkets to sell on the black market. Experts say better law enforcement is needed to stop poaching. Consumers, especially in Asia, need to stop buying these illegal and harmful goods.
Another way is to slow human population growth. This sounds weird but more people means more food and more land means more resources. Population growth is one of the main causes of earths extinction crisis. Fun fact, the population in 1980 was 4 billion. Its now 7.4 billion and is on its way to 9.7 billion by 2050. We needlessly use resources we know are harmful such as plastics. Plastics are clogging the worlds oceans. Some researchers expect there to be more plastic than fish in the ocean, by weight, in the year 2050.

1)What questions did you need to research in order to research your topic?
I searched up, what ways can we stop extinction. I also researched how long does earth before it ends.
2)What new or familiar digital tools did you try to use as you worked through this project?
A new tool I used was the library data base and pexels for my image. And a familiar tool I used was google.
3)What was the process you used to investigate the topic?
Start by finding 3 useful resources and taking notes. then start putting the notes together to make the project look good.
4)How did you verify and cite the information you found?
I verified by checking for grammar mistakes to make sure its not fake.
5)How did the process of completing this challenge go? What could you have done better?
The process went good at the end when it got more simple to understand. I could have done better with library data base.
