The 12 Days of Family Planning

On the first day of Christmas, my true love discussed with me:
Having kids only if and when we’re ready.

On the second day of Christmas, my true love discussed with me:
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the third day of Christmas, my true love discussed with me:
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the fourth day of Christmas, my true love discussed with me:
4 emergency contraception options,
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the fifth day of Christmas, my true love discussed with me:
5 times our carbon footprint,
4 emergency contraception options,
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the sixth day of Christmas, my true love discussed with me:
6 mass extinctions,
5 times our carbon footprint,
4 emergency contraception options,
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the seventh day of Christmas, my true love discussed with me:
7.5 billion people on the planet,
6 mass extinctions,
5 times our carbon footprint,
4 emergency contraception options,
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the eighth day of Christmas, my true love discussed with me:
81 percent of freshwater species lost,
7.5 billion people on the planet,
6 mass extinctions,
5 times our carbon footprint,
4 emergency contraception options,
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the ninth day of Christmas, my true love discussed with me:
9.8 billion people by 2050,
81 percent of freshwater species lost,
7.5 billion people on the planet,
6 mass extinctions,
5 times our carbon footprint,
4 emergency contraception options,
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the tenth day of Christmas, my true love discussed with me:
10 thousand threatened plant species,
9.8 billion people by 2050,
81 percent of freshwater species lost,
7.5 billion people on the planet,
6 mass extinctions,
5 times our carbon footprint,
4 emergency contraception options,
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the eleventh day of Christmas, my true love discussed with me:
11 forms of hormone-free contraception,
10 thousand threatened plant species,
9.8 billion people by 2050,
81 percent of freshwater species lost,
7.5 billion people on the planet,
6 mass extinctions,
5 times our carbon footprint,
4 emergency contraception options,
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

On the twelfth day of Christmas, my true love discussed with me:
12 percent of bird species threatened,
11 forms of hormone-free contraception,
10 thousand threatened plant species,
9.8 billion people by 2050,
81 percent of freshwater species lost,
7.5 billion people on the planet,
6 mass extinctions,
5 times our carbon footprint,
4 emergency contraception options,
3 types of long-acting reversible contraceptives,
2 hundred thousand people added to the planet every day,
And having kids only if and when we’re ready.

2282. How Can You Save Endangered Species... In Bed?

By Center for Biological Diversity, April 13, 2016

Saving wildlife is sexier than you might think. How sexy? Every time you slip between the sheets with that special someone you can be a hero for wildlife – as long as you protect yourself and the planet. Every day, 227,000 humans are added to the planet and in the United States alone, nearly half of all pregnancies are unplanned. 

2126. Large Predators Limit Their Own Numbers

By Janet Fang, IFLScience!, March 2, 2015

Unlike small mammals who multiply like bunnies or some predators who’s boom or bust depends on said bunnies, large carnivores like lions and wolves keep their own numbers in check. According to a new work published in Oikos last week, population control is what distinguishes “apex predators” from the rest. 

Researchers have traditionally assumed that the densities of the largest of predators are determined by the availability of their prey supply, but recent studies seem to contradict a bottom-up control. And now, an international team led by Arian Wallach from Charles Darwin University proposes an alternate view: Apex predators naturally have the capacity to limit their own population densities—or self-regulate—helping to keep their ecosystems in balance.

The team tested their idea using a set of life-history traits that might contribute to self-regulation in mammalian carnivores, such as birth rate and investments by parents. They gathered research on more than a hundred species, Science reports, from skunks and stoats to polar bears, panthers, and wolves living in Yosemite. They found that an average weight of 13 to 16 kilograms (29 to 35 lbs) marks a transition between self-regulated carnivores and those that are regulated by external factors.

Small carnivores have fast rates of development and reproduction, as well as higher densities. Large carnivores, on the other hand, have slow reproductive rates and development, extended parental care, sparsely populated territories, and a natural tendency towards infanticide, reproductive suppression, and cooperative hunting, the authors write. 

About half of these large carnivores control the numbers within their group by only letting certain members breed, Science explains. Many of the bigger predators are known to have complex social systems: Dominant female wolves and hyenas, for example, kill the pups of subordinates, and in many large carnivores, the group ends up raising the alpha female’s (or pair’s) pups together. Self-regulation in large carnivores, they conclude, likely ensures that the largest and fiercest never overexploit their resources.
