It is aimed to make Biosphere2( that multiple species living in the closed environment live with ecological balance) that can be placed on the desktop. To keep it long term , it will be able to manage temperature and light. And it has various sensors, so we will be able to obtain information(biosphere recipe)to make longer .

I do not like schedule.I use only task list.
how will it be evaluated?Can ecological balance be maintained for more than half a year or not
