Answer:
A common method of illegal dumping is throwing garbage directly into a river or stream, this causes oceanic pollution and leads to the death of marine life.
Waste that is dumped illegally often contains dangerous and toxic substances, which soak in all the oceanic oxygen. This leads to depletion of oxygen available to mammals and other fish causing them to die in their natural habitat. Dolphins, seals and other sea life also get caught or choke on plastic material such as plastic bags and rings, causing debilitating health or death. Every year, according to reports, more than one million seabirds are being killed by ocean pollution.
Toxic substances can be released from the waste that is illegally dumped, this is damaging to people who come into contact with these substances. Children are most notably at risk if garbage is dumped in a public area such as a park.
