Answer:
The two types of pollution that are demonstrated in this real world example are:
- Toxic pollution and
- Sediment pollution.
Explanation:
- The new development that is being built is the main source that causes the pollution of stream through sediment process.
- Sediment is the process of carrying the waste through erosion and decomposition of plants and animals.
- Similarly the leaked oil antifreeze is highly toxic and hazardous to environment.
- The acid presence in the antifreeze onto the pavement is very harmful for the micro organisms as well.
