Many impacts can be brought by global warming, here I would introduce two impact each on the aspect on ecosystem and agriculture.
On ecosystem:
1. Shift in distribution of plants:
The changes in climate brought by global warming will alter the natural distribution limits for vegetation. For example, forests are moving north into the ;and that was once Arctic tundra, while the growing season increased in northern high latitudes.
2. Extinction or endangerment of species
Species may not be able to cope with climate change unlike human, hence intolerance of the increasing temperature may led to the extinction of spices. For example, coral reef cannot survive under temperature over 30 degree Celsius hence facing the danger of extinction.
On agriculture:
3.Farm production lowered
A warmer climate would lead to a loss of soil moisture hence increasing the erosion rate, and the dry soil will lower the land productivity as crops cannot grow on these barren land, especially water thirsty crops such as rice.
4.Farm production destroyed
Pests may become more active given the shorter and warmer winter, while floods may be present more often given the rapidly rising sea level and the instability of the climate.
Hope it helps!

PUT THIS IN YOUR OWN WORDS SO YOU DON'T GET COPYRIGHTED
Mr/Mrs.logger, in this letter I would like to persuade you to stop cutting down trees. It will help the economy, you can find a new job, and you will understand that being greedy is not okay. Keep reading on to understand why. Thank you!
Cutting down trees in this state is illegal. I understand you are trying to help your family by making money. But, there are many other ways to do so like, helping people build fences, go to a store and be a cashier, help people move things, etc. Finding another job could help you put food on your family's table and not send you to jail.
If that didn't persuade you to look at the Amazon Rainforest for refrence, people took down those trees to help support their family but it only ended up destroying another family's home. All of these creatures lost their homes that they had to keep their family safe, warm, alive. But, all those loggers did was put these animals on the brink of extinction just to help their own families. And, the Amazon Rainforest is very important and needed in this world. It is one of the many reasons that earth is habitable, it's water cycle's, the many tree's giving off Co2, it is also home to 30 million people! and over 10% of the world's biodiversity! That's a lot. And, the tree's that you are cutting down could someday be a rainforest that will contain millions of people. So really think about it, think about what you are doing to the world, think about how you can fix it.
So I hope that I was able to persuade you to learn to do something else that won't ruin or economy, I mean we all mess up with something that will make our Co2 footprint bigger but there are many ways to try and fix that like tyring to make a compost garden, plant a garden, do anything that will help your family and the animals/plants surrounding you.

Answer:
Various advantages and disadvantages are given as under
Explanation:
<u>Pros</u>:
- As Genetically modified crops are genetically disease resistant they have been proven safe through testing and use.
- They increase the nutrient contents and reduce the worldwide hunger levels, also lower prices of food.
- They lead to environmental benefits such as reduced pesticides use and lower carbon emissions
<u>Cons</u>:
- They have not been proven safe for human consumption through trials.
- Genetically modified crops can lead to the development of various food allergies in the body.
- Increased use of toxic herbicides and pesticides damages soil fertility.
