B．More studies need to be made about the fish killer.
C．It is proved that the algae are reducing fish populations.
D．Humans have already been affected by the toxin.请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：B
解析：推断题型见第五段：To understand the killer algae further，scientists must fully characterize their toxin and determine what stimulates them to attack．They also need to know if the algae are hurting fish populations，and whether pollutants make them more likely to attack．见下划线部分，因此可知还有更多的研究要做，因此B为答案。
