It's 2016, yet girls around the globe might still think it's impossible to grow up and become presidents.

The Women In Parliaments Global Forum (WIP) has launched an initiative called the Leadership Campaign to address that very issue. The initiative combats gender parity in government, launching just in time for International Womens Day.

In efforts to illustrate why gender parity in politics is critical for the worlds entire population, WIP invited all male Heads of State to participate in submitting testimonies on the importance of increasing the number of women in political leadership positions around the world.

More than 50 presidents and prime ministers have responded to WIP, a global network of female parliamentarians.

While progress for gender parity has been made, both upper and lower houses of parliaments globally are far from fairly representing their constituents: According to the Inter-Parliamentary Union , in 1995, women held about 11 percent of parliamentary seats worldwide; in 2016, they occupy just under 23 percent.

To break this down further, about 14 percent of these seats won by women in the past year were in countries without gender quotas .

See a few responses from world leaders below.

"We need more women in parliament and as political leaders because they play a key role in the education of new generations and in society building, contributing in its growth and well-being and in its social, economic and cultural development." -- Jos Eduardo dos Santos, President of Angola
