Mrs Netani, presentation was a good topic, Toxic Effects are indeed very dangerous
for the survival of living things in this world, I am very interested in the topic that
you raised, My field is music, I play in the wave area, hopefully one day we can
collaborate to overcome this problem, because waves can neutralize the air that
contains poison, Thank you
