Endangered Animals

Yesterday in class we watched a video about how herbicides can be harmful to frogs and that there are other things we can do like use boiling water, vinegar or pull the weeds out. Scientists suggest we should not use herbicides but in the end society decides whether or not we use it.
We learnt about endangered animals and disscussed what people could do to help to do to prevent it like making safe places for them to live. Then we watched another short video about how many of the endangered species are found in the oceans and that they once killed 3/4 of whales without realizing it.
We then read about bald eagles, there were a lot in the 1700's and 1800's but there was decline in the 1900's. The causes of this might have been because the eggs of the eagles would become thin and would brake easier due to the toxins.
