There is now compelling evidence to show that humanity's impact on the Earth's atmosphere, oceans and wildlife has pushed the world into a new geological epoch, according to a group of scientists.
The question of whether human's combined environmental impact has tipped the planet into an "Anthropocene"
- ending the current Holocene which began around 12,000 years ago.
Humans have introduced entirely novel changes, geologically speaking, such as the roughly 300m metric tons of
plastic produced annually. Concrete has become so prevalent in construction that more than half of all the
concrete ever used was produced in the past 20 years.
What cost to the environment might we expect from the tons and tons of plastic that is produced annually?

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
