Dogs are naturally swimmers, and ever since Suming had thrown De Fu and Wang Cai into the water once, they had completely fallen in love with Shuijun Lake. They spent most of their time soaking in the lake, no longer caring to frolic with the cats.
Suming even specially ordered a set of small life jackets for them, so now they could cool off in the water and occasionally play the role of lifeguards.
That morning, Wang Cai brought back a plastic snack bag from the water and barked at a few tourists rowing on the lake. That's when Suming learned that some uncivilized tourists not only fed the fish but also threw trash into the lake.
If fish ate the plastic bags, they would certainly be doomed. Even if the fish didn't eat them, such items were hard to decompose naturally. They would accumulate on the lakebed, and over time, they would be difficult to clean up, causing significant water pollution.
